• 3/4 cup (180 ml) warm water, plus up to 2 tbsp more if needed
• 1 tbsp neutral oil
• 2 tbsp sour cream (optional but recommended for tenderness)

Filling

Caramelized Onion Topping

• 2 large yellow onions (about 600 g), thinly sliced

• 1 tbsp neutral oil
• 1/2 tsp fine sea salt
• 1–2 tbsp water, for deglazing as needed

To Cook and Serve

• 1 tbsp kosher salt (for boiling water)

• 1 cup (240 g) full-fat sour cream, chilled
• 2 tbsp finely chopped chives or parsley (optional)
• Freshly ground black pepper, to finish

Step-by-Step Instructions

Step 1: Make and rest the dough

In a large bowl, whisk flour and salt. Make a well and add the egg, sour cream, and oil. Add the warm water while mixing with a fork until shaggy. Tip onto a counter and knead 3–5 minutes until smooth and slightly tacky. If dry, knead in up to 2 tbsp more water; if sticky, dust lightly with flour. Wrap or cover with a bowl and rest 30 minutes to relax the gluten.

Step 2: Cook and mash the potatoes

Place potatoes in a pot, cover with cold water by 1 inch, and add 1 tsp salt. Bring to a boil, then reduce to a lively simmer and cook 12–15 minutes until very tender. Drain thoroughly. Return potatoes to the hot pot over low heat for 1 minute to steam off excess moisture, then mash or rice until perfectly smooth.

Step 3: Caramelize the onions

While potatoes cook, melt 3 tbsp butter with 1 tbsp oil in a wide skillet over medium heat. Add onions and 1/2 tsp salt. Cook, stirring often, then reduce to medium-low and continue 25–30 minutes until deep golden and jammy. If brown bits stick, splash in 1–2 tbsp water to deglaze. You will have about 1 to 1 1/2 cups. Reserve 3/4–1 cup for topping; finely chop about 1/2 cup to mix into the filling.

Step 4: Make the filling

To the warm mashed potatoes, add twaróg, 2 tbsp butter, the chopped caramelized onions, 1 tsp salt, and 1/2 tsp pepper. Mix until creamy but not wet. Taste and adjust seasoning—filling should be well seasoned. Cool to room temperature (10–15 minutes) so it is easy to scoop and seals well inside the dough.

Step 5: Roll the dough

Divide the dough in half. Keep one half covered. On a lightly floured surface, roll the first half to 1/16–1/8 inch thickness. Cut 3 inch (7.5 cm) circles with a cutter or rim of a glass. Gather scraps, cover, and let them rest 5 minutes before re-rolling to prevent spring back.

Step 6: Fill and seal

Place about 2 tsp filling in the center of each round. Lightly dampen one half of the edge with water. Fold into a half-moon, pressing out air around the filling as you seal. Crimp firmly with fingers. Arrange on a lightly floured tray and cover with a towel so they do not dry out while you finish the rest.

Step 7: Boil the pierogi

Bring a large pot (4 quarts/3.8 L) of water to a boil (212°F/100°C). Add 1 tbsp kosher salt. Working in batches of 8–10, drop pierogi in, stir immediately so they do not stick, and cook until they float plus 2 minutes (about 3–4 minutes total). Lift out with a slotted spoon to a buttered tray and toss gently with about 1 tbsp of the melted butter to prevent sticking.

Step 8: Finish with butter and onions, then serve

Warm the remaining 2 tbsp melted butter in a skillet over medium heat. Add boiled pierogi and toss 1–2 minutes for a glossy, lightly golden finish. Transfer to a platter, blanket with the reserved caramelized onions, grind over a little pepper, and add a generous spoon of cool sour cream. Sprinkle with chives or parsley and serve immediately.

Pro Tips

• Weigh your flour if possible for consistent dough; otherwise add water gradually to get a soft, supple dough.
• Dry the potatoes after boiling by returning them to low heat briefly—this prevents a watery filling.
• Chill the filling slightly so it scoops cleanly and keeps the dough easy to seal.
• Test-cook one pieróg to check seasoning and texture before shaping the whole batch.
• Seal firmly and crimp well; any gaps will let water in and the filling out.

Variations

• Smoky bacon and onion: Crisp 4 oz (115 g) smoked bacon, chop, and fold into the caramelized onions for topping.
• Herb boost: Add 2 tbsp finely chopped dill or chives to the filling, or 1 tbsp minced herbs into the dough.
• Crisp finish: After boiling, pan-sear pierogi in butter 2–3 minutes per side for lightly crisped edges before topping.

Storage & Make-Ahead

Refrigerate shaped, uncooked pierogi on a floured tray covered with plastic up to 24 hours. To freeze, arrange uncooked pierogi on a parchment-lined sheet in a single layer; freeze until solid, then transfer to a zip-top bag for up to 2 months. Cook from frozen in boiling salted water, adding 1–2 extra minutes. Leftover cooked pierogi keep 3 days in the fridge; reheat by pan-sautéing in butter until warmed through.
